Description
The objectives of this research were: study of radiation induced structural changes in weld metal and study of recovery of radiation induced structural changes due to recovery annealing of weld metal. The results obtained enable the following conclusions: the dominant type of radiation induced structural changes occurring in Russian weld metals irradiated in the conditions typical for operating WWER-440 reactors are the increased densities of disk shaped and rounded precipitates; the kinetics of structural changes due to re-irradiation of weld metal after recovery annealing can be distinguished from the kinetics changes due to initial irradiation by lower rate. The latter can be explained by incomplete recovery of radiation induced structural changes due to recovery annealing at 475 deg.C
